Receipts machine, wireless network and ground control station；The control device is connected by serial ports one with described image process chip, the control
Control equipment is connected by serial ports two with the GPS receiver；The control device include control chip and respectively with the control
Power supply that coremaking piece is connected, serial port circuit, LCD display circuit, usb circuit, storage device, clock circuit, JTAG emulation
Interface.
The camera interface includes parallel data grabbing card and image sensor interface；The data of the parallel data grabbing card are defeated
Entry format is bayer forms and YUV (YCbCr) form.
The VC0706 chips of the model Z-Star Microelectronics of described image process chip.
The camera is CMOS cameras.
The control chip is the TMS320DM8148 chips of the U.S. " Texas Instrument " production.
The beneficial effects of the invention are as follows：Small, transmission rate is high, long transmission distance；It can realize that image and positioning are believed
Collection, the transmission of breath；It is stable and reliable in work.
Brief description of the drawings
Fig. 1 is the structure diagram of the embodiment of the present invention.
Fig. 2 is the structure diagram of control device in the embodiment of the present invention.
Embodiment
Explain below in conjunction with the accompanying drawings to the embodiment of the present invention.
Referring to Fig. 1, holder that the camera system based on unmanned plane of the embodiment of the present invention includes being installed on unmanned plane,
CMOS cameras, VC0706 picture processing chips, control device, ground control station.
In the present embodiment, camera is fixedly mounted on holder.Camera is using the high resolution CMOS camera of 12V as boat
Shooting camera, 28mm tight shots, camera lens are 1/3 English using million grades of cctv camera lenses, 3,000,000 pixels, size sensor
It is very little, support parallel or serial 1080P outputs.
Camera interface has two, one of them is parallel data grabbing card, supports two kinds of input formats：1) original pixels form
That is bayer forms, highest support 16, are inputted in the present embodiment using the data of form 12,2) YUV (YCbCr) form, branch
The input of 4: 2: 2 forms is held, data are 8 or 16；Another interface is image sensor interface, in the horizontal direction and vertically
32000 pixels of highest are supported at the same time in direction.
Picture processing chip uses the VC0706 picture processing chips of Z-Star Microelectronics.Picture processing chip is referred to by control
Order control VC0706 picture processing chips realize that control camera is taken pictures, while can also carry out the video and image of camera shooting
H.264 and JPEG the tasks such as processing and Digital Image Transmission are compressed, its image compression format supported is.
Control chip is electric with power supply, serial port circuit, LCD display circuit, usb circuit, storage device, clock respectively
Road, JTAG emulation interface are connected, as shown in Figure 2.
In the present embodiment, " Leonardo da Vinci " series that control chip was released using manufacturer of the U.S. " Texas Instrument " in 2011
Chip TMS320DM8148.The video that the chip can provide under 3 watts is 1080p60 frame single videos stream, 3
720p30 frame synchronization video flowing or the combination of multiple low resolution video flowings.
The power supply being connected with TMS320DM8148 control chips uses TPS7333QD chips, and external+5V voltages are converted into
+ 3.3V, gives circuit board offer+5V ,+3.3V voltage, and using voltage of the bleeder circuit to CPU offers+1.8V, meets that system supplies
Electricity requires.
Whether just serial port circuit judges camera work by RS-422 or RS-232 signals and camera part real-time Communication for Power
Sent often and by trigger button and start shooting signal, returned to shooting number, finally send LCD display circuit to be shown.
The LCD display circuit model LQ080V3DG01 of selection, drives due to carrying a LCD inside TMS320DM8148
Movement controller, its interface can be connected directly with the LCD of monochrome, gray scale, colour STN types and colour TFT types.
Clock circuit is divided into two parts, for control circuit, selects the crystal oscillator of 22.1284MHZ, is
TMS320DM8148 provides clock cycle signal.
